4 Claims.

Our invention relates to oil burners and particularly Vto the type of burner adapted for use in household ranges.

In the` burner of this character commonly in use, the heat is generated in concentrici combustion chambers generally lincluding two burner units, and the heat from each combustion chamber,vrising, heats thetop of the stove unevenly in concentric areas over the chambers, the areas between andat the ends being heated by conduction of the heatthrough the metal. Moreover the water back is inadequately heated, as each burner unit radiates the heat tothe lwater back, from a maxrnumrin Va plane normal tothe surface of the waterback and passing through the axes of the burners, varying in either direction to a minimum between burners and at the ends of the nre box.

One object of our invention is to provide a burner that will more uniformly heat the entire area of the stove top above the fire box, and at the same time radiate a uniform heat to the water back.

' A second lobject is to provide a burner from which the carbonized oil may be readily removed, not only from the burner proper but from the heating chamber from which the oil is supplied to each combustion chamber.

A further object is to provide a heating chamber f having independent connections to each combustion chambers to deliver an approximately uniform heat to the stove top and the water back. Other novel features will appear in the accompanying specifications and claims and the drawing forming a part thereof.

We do not conne ourselves to theparticular embodiment described Vand shown herewith, as modications may be made within `the scope of the appended claims.

In the drawing, v

Fig. 1 is a sectional elevation substantially en the lines I--I of Fig. 2.

Fig. 2 is a plan view of a preferred embodiment of our invention with parts broken away to feature certain parts. I

Fig. 3 is a sectional end elevation, substantially on the lines 3 3, Fig. 2.

Fig. 4 is a plan view of one form of burner stand having means for adjusting the burner in the re pot. 1

In the drawing we have shown and have described a form in which two series of burners are s to the openings.

disposed on opposite sides ofV a median line and each series connecting with independent heating chambers, but we may use a single series connecting each'burner with a single heating chamber, all having the essential features herein de 5 scribed and shown. v

Referring to the drawing, I0 is a burner base having supporting means including the post II, and the stand I2, and an eccentric sleeve I3 through which the post-extends Aand is held in adjusted position vertically by a set screw I4. The set screw I5 secures the sleeve in some laterallyY adjusted position of Ythe burner base. No claim for novelty is made on this supporting means and other well known means may be substituted.

The plate IIJ is substantially rectangular in outline and formed on its upper surface with a plurality of elongated troughs I6, having walls parallel toi two sides of the plate and to each other and connected at their ends. Combustion chambers formed with perforated walls I8, extend upwardly from each trough and are supported by the walls thereof, the chambers alternating with air spaces 20 between combustion chambers. The walls I8 are formed from sheet metal commonly used in oil burners, theperforations being indicated in part in Fig.Y 1.

The cover 2! is formed with slots 22 over each combustion chamber, and is supported by the walls of the several combustion chambers.

In this embodiment we have shown two series of troughs and combustion chambers disposed in their elongated dimension normal to a ymedian line across the plate', each series of troughs being s independently connected by ducts 220 with respective oil preheating chambers 23, 2d, the wall 25 separating the chambers. Y I

Each chamber is provided with independent inlets 26, 2l through which oil may be supplied from arsourceV of supply through the usual connections. Each chamber is provided at each end. with openings 351, 3| through which access may be had for cleaning the chambers of sediment or carbonized oil, the plugs 28, 29 serving as closures The oil entering the chambers spreads in a lm as it passes to the ducts connecting the several burners, and when the burners are operating, the l radiated heat raises the temperature of the walls of the preheating chambers and is transmitted to the inflowing oil, raising its temperature to or near the vaporizing point before entering the troughs. In the embodiment shown, either series of burners or combustion units may be operated 55' by the usual arrangement of piping and needle valves to admit oil to one or both heating chambers.

With our burner, a greater proportion of the heat from the units contiguous to the water back is radiated uniformly to heat the walls of the water back, and at the same time a more uniform heating of the top of the stove is possible as well as the front Wall of the range oven.

Having thus described our invention, We claimz- 1. An oil burner comprising a base plate formed with a plurality of independent elongated fuel troughs of substantially rectangular outline, and in parallel relation; perforated walls extending upwardly from and supported by the walls of respective troughs, and forming independent parallel combustion chambers separated by air spaces; a heating chamber formed in the plate and having individual duct connections to each trough and an-inlet through which fuel oil may flow from the source of supply.

2. An oil burner comprising a base plate formed with a plurality of independent elongated fuel troughs of substantially rectangular outline, and in parallel relation; perforated Walls extending upwardly from and supported by the walls of respective troughs, and forming independent parallel combustion chambers separated by air spaces; a heating chamber formed in the plate and extending across normal to the median lines` of the troughs and having individual duct connections to each trough and an inlet through which fuel oil may iiow from a source of supply.

3. An oil burner comprising a base plate of substantially rectangular outline, and formed with a plurality of independent elongated fuel troughs in parallel relation to opposite sides of the plate; perforated walls extending upwardly from and supported by the walls of respective troughs, and forming independent parallel combustion chambers separated by air spaces; a heating chamber formed in the plate and extendingacross normal to the median lines of the troughs and having individual duct connections to each trough and an inlet through which oil may flow from a. source of supply.

4. An oil burner comprising a base plate of substantially rectangular outline, and formed with a plurality of elongated fuel troughs in parallel relation to opposite sides of the plate, and in Series on either side of a median line across the plate;. perforated Walls extending upwardly from and supported by the Walls of respective troughs, 'f and forming parallelcombustion chambers sep arated by air spaces; and oil preheating chambers formed in the plate and extending thereacross normal to the median lines'of the troughs and separated from one another by a partition wall to form two compartments separating each series of troughs, each compartment having duct connections with each trough in the respective series of combustion lchambers thereadiacent,

said preheating chambers each having an inletl
